Ammonium and phosphonium halides when heated with excess dimethyl or diethyl phosphite can undergo anion exchange as a result of alkylation of halide ions with dialkyl phosphites. Experimental data were obtained, that cast some doubt in the commonly accepted opinion that reactions of tertiary amines and phosphines with dihalides in apolar media result in exclusive formation of monosalts.

This application relates to an improvement in the preparation of quaternary ammonium alkene halides which are used in the production of cationic starch. The quaternary ammonium alkene halide product is recovered in a water solution which reduces exposure to and handling of the product by production workers, both in the manufacturing plant and in its subsequent use in a starch processing plant.
